A video posted yesterday on YouTube shows the grisly shooting of a dog by a police officer in Hawthorne, California.

The 130-pound, 3-year-old Rottweiler named Max was shot to death after he escaped through a window in a parked car and ran over to his master, Leon Rosby, who was being arrested for filming the scene on his phone.

The video (watch original on YouTube) shows Rosby, 52, walking his dog Sunday around 7 p.m. near a house with several police squad cars parked outside.

He is seen filming the scene in order ‘to make sure nobody’s civil rights were being violated,’ he told DailyBreeze.com.
